JOHN LACEY AND GEORGE E. CORNELL, OF CHICAGO, ILLINOIS; SAID LACEY ASSIGNS HIS RIGHT TO SAID CORNELL.

IMPROVEMENT IN COMBINED BUSHES AND WRENCHES FOR BUNGS.

Specification forming part of Letters Patent No. 118,617, dated August 29, 1871.

To all whom it may concern:

Beit known that we, JOHN LACEY and GEORGE B. CORNELL, ofChicago, county of Cook and State of Illinois, have invented a new and valuable Improvement in Metallic Bushings for the Bun gs of Casks, &c., and in Wrenches for operating the same; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l is a bottom view of the wrench. Fig. 2 is a top view of the bushing; and Fig. 3 is a longitndinal section, showing the application of the wrench to the bushing.

Our invention has relation to means for protecting the bungs of casks, 850.; and it consists in an improvement in metallic bushings for lining the bungs, and in a wrench for turning said bushing, which is cast with a screw-thread, into the bung-hole.

a of the drawing designates the bushing-a tapering thimble or rin g of metal, provided with a lianch, b, at its larger end, and having a screwthread, 0, on its outer surface, which screw-thread is cast on the bushing in the mold, and is capable of immediate use Without other finishing. The flanch bis rounded oif at its edge, and is provided at some point in its extent with a V-shaped notch, 11, extending in to the screw-thread. E represents the wrenclrbar, consisting of the slotted plate 0 and the shankjl The metal of the shank, at its junction with the plate, forms a downward V-shaped projection, 1, whose point extends forward toward the center of the plate 0. F represents a tapering core of metal, adapted to fit the bung-bushing a, and secured to the plate 0 by means of the bolt h and its nut. This core is made separable from the wrench-bar, in order that, by providing a number of cores of different sizes, the same wrench may be used for bushings of different diameters. Provision is also made, by the slot is, for moving the bolt toward the angular projection l, which becomes necessary when a smaller core is substituted for a larger one.

The wrench is applied by inserting the core into the opening through the bushing, and turning it until the projection 1 falls into the notch (I. By means of the core the bushing is kept steady, and is readily prevented from assuming an oblique position in the bung-opening; at the same time the operator is enabled to get a better hold on the bushing than by means of the wrenches in common use, which are apt to slip from their seats when used on such difiicult work as turning a rough'cast screw into place.

WVhat we claim as our invention, and desire to secure by Letters Patent, is-

The combination, with the notched bung-bushing a, of the wrench, consisting of the bar E having the slotted plate 0 and angular projection l, and the removable core F, substantially as specified.
